July 28th, 1910, 467 eggs, after which it died. He found 
that as a rule the eggs hatched in about five months after 
being laid, but a few were hatched sooner. The females 
generally began ovipositing when they were five or six months 
old. 
Deias From New Guinea Movuntains.—Dr. K. Jorpan 
exhibited 46 forms of Delias from the mountains of New 
Guinea. The first of these peculiar mountain species were 
discovered late in the nineties in the Owen Stanley Range, 
British New Guinea, by a German, E. Weiske, and described 
by C. Ribbe in 1900, with the exception of D. albertisi and 
D, discus, which had already been known for some time. 
Since then A. S. Meek and lately also Messrs. Pratt have 
considerably added to the number. Whereas in other districts 
of the Oriental Region at the most seven or eight species 
generally four to six) may be found in any locality, a sur- 
prising number are met with in the mountains of New Guinea 
from 3,000 or 4,000 ft. upwards. In suitable localities of 
the Owen Stanley Range no less than 24 species have been 
obtained, of which 18 are confined to the higher altitudes. 
These mountain Delias are known from three ranges—the 
Owen Stanley Mountains in British territory, the Snow 
Mountains in Southern Dutch New Guinea, and the Arfak 
Mountains in the north-west of the island—and we have also 
two species from a high altitude on the German-British 
boundary. It is most interesting to find (1) that each moun- 
tain range has its own forms, the geographical differences 
often being surprisingly great and undoubtedly of specific 
value; (2) that most of these forms represent each other, 
although they may be specifically distinct, and (3) that several 
species are known only from one or two ranges. 
The exploration of these mountains being very incomplete, 
we may expect that representatives of most of the species as 
yet only known from one or two places will be obtained in 
the other mountains as well. <A similar assemblage of Delias 
undoubtedly also exists in those high chains of the island 
which the collector has not yet touched. 
Braziuian Spuinetps.—The Rev. A. Mites Moss exhibited 
the following Sphingids from Para, which had been identified
